For a long time before I met my husband, I had a fantasy I would run through while masturbating to help me get to climax. Born from some internet searches as a teen that ended up in the anime tentacle rape porn realm, I created a series of specific scenarios in my head that I could match my bodies actions to so that I could fully immerse myself into the fantasy.
Laying on my back in bed with my head near the edge, I close my eyes and imagine I'm walking down a thick forest path. There are vines hanging down, a large thick canopy above my head blotting out sun except for some streams of sunlight. It's warm and slightly humid, I feel the sweat on my neck and back as I walk. I start to hear sounds around me; rustling in the bushes, birds becoming agitated and flying away. The air is thick and sweet in a way that makes me slightly dizzy. My apprehension grows as I walk, hearing all sounds suddenly stop. The silence is astoundingly noticeable.
In a flash, I feel my legs get pulled out from underneath me - I'm ripped down through the brush and swung upward into the air. Startled, I see a thick vine wrapped around my legs as I dangle, looking around I see many vines moving slowly in the trees around me.
In the real world, I move slightly backward off of the bed, letting my head hang. The blood rushing to my head suddenly reinforces my mental image of hanging upside down while I clench my legs shut as if to stop the vines advance. I can feel my panties start to get wet in anticipation, the blood in my head and neck making me slightly dizzy.
The vines start to work their way up my body, wrapping around my breasts, my neck, and my thighs. They prod and force their way into the crevices of my tightly clenched legs, wrapping fully around my inner thigh, pushing my pussy together and coming out the back to cup my ass. My legs are still tightly closed despite the vines moving and vibrating on the sensitive inner skin of my thighs, which I simulate in reality by pulling my panties up, feeling the pressure of the clothing & seams against my clit and inner thighs.
